The submersible buoy with turbulence instrument is an effective and a long-term observation platform of the turbulence in deep sea and plays an important role in marine scientific research.The current development of turbulence instruments at home and abroad and shear probe measurement principle were briefly introduced.According to the measurement data by turbulence instruments in submersible buoys,the factors affecting the measurement results of turbulence instruments were analyzed.The methods to reduce noise pollution were discussed.Aiming at the reduction of noise caused by the vibration of cable transmission,the application of low temperature water damping material was proposed.The experimental data indicate that adding damping material can effectively reduce the influence of vibration on the measurement accuracy.
